Summary
Transcatheter mitral valve edge-to-edge repair (TEER) is challenging in mirror-image dextrocardia. This case demonstrates successful TEER with specific adaptations for this rare anomaly.
Area of Science:
- Cardiology
- Interventional Cardiology
- Congenital Heart Disease
Background:
- Mirror-image dextrocardia is a rare congenital anomaly.
- Severe mitral regurgitation (MR) presents significant challenges for transcatheter mitral valve edge-to-edge repair (TEER).
Observation:
- A 72-year-old woman with mirror-image dextrocardia and severe MR underwent TEER.
- The procedure required modifications in echocardiography, septal puncture, and clip delivery to overcome anatomical reversal and the "aortic hug" phenomenon.
Findings:
- Successful TEER was achieved in a patient with mirror-image dextrocardia and severe MR.
- Procedural adaptations were crucial for catheter navigation and effective leaflet grasping.
Implications:
- TEER in mirror-image dextrocardia necessitates tailored approaches.
- Successful outcomes depend on operator experience and advanced spatial reasoning skills.

01:20Mitral Regurgitation I: Introduction
55
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

51
Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...

82
Mitral regurgitation (MR) is a condition where the mitral valve does not close properly, leading to the backward flow of blood from the left ventricle into the left atrium during systole. This condition can arise from various causes, including rheumatic fever, infective endocarditis, or degenerative valve disease. Effective nursing management is crucial to optimizing patient outcomes and involves comprehensive assessment and targeted interventions.Comprehensive Patient AssessmentA detailed...

01:22Mitral Stenosis I: Introduction
35
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

37
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...
